Embodiment

[0014] Embodiment: a kind of processing method that adopts water-soluble antibacterial monocarboxyl chitosan to produce antibacterial deodorant polyester fiber, comprises the steps:

[0015] (1) Raw material ratio: Dissolve light yellow monohydroxy chitosan solid slices in water to make a 75% aqueous solution of water-soluble antibacterial monocarboxy chitosan;

[0016] (2) Mixing and drying of raw materials: fully mix polyester melt with 75% water-soluble antibacterial monocarboxyl chitosan aqueous solution for half an hour, and then put it into a vacuum dryer for drying. The pre-drying temperature is 106°C. The drying time is 2 hours, then the temperature is raised to 120°C and dried for 5 hours, and the moisture content of the dried polyester melt is kept below 30ppm;

[0017] (3) Melt spinning: transport the dried mixed raw materials in step (1) to six-box screw extruders for heating and melting, and control the temperature from one to six. The temperature of each box is: ...

Abstract

The invention relates to a process method for producing antibacterial and deodorant polyester fibers by adopting monocarboxy-chitosan. An antibacterial and deodorant polyester fiber production process comprises the following processing steps of mixing a polyester solution and a water solution of 75% water-soluble antibacterial monocarboxy-chitosan and drying, fusing and spinning, and coldly and hotly molding and the like. The method is simple to operate, rapid in reaction speed and easy to control; prepared carboxy-chitosan modified cotton fibers have lasting and efficient antibacterial activity and good wearability, are green and environmentally friendly, and overcome negative effects on the wearability of the polyether fibers and human health, caused by a chemical cross-linking agent. The process method is wide in raw material source; crustacean organisms are renewable resources and a production process is environmentally friendly; and the process method is low in production cost, low in production energy consumption and remarkable in environment load properties.

Description

technical field [0001] The invention relates to a production process of antibacterial and deodorizing polyester fibers, specifically, a process for producing antibacterial and deodorizing polyester fibers using monohydroxy chitosan, and using monocarboxy chitosan to prepare durable antibacterial and deodorizing fibers The method for polyester fiber belongs to antibacterial chitosan and the modification technology applied to polyester fiber. Background technique [0002] As one of the three main fibers in synthetic fibers, polyester is widely used in clothing fabrics and other non-clothing fields because of its excellent physical and chemical properties. Since its inception, polyester products have also been used by downstream users as the main textile raw material to weave various textiles due to their good drapability, high strength and crispness. With the globalization of the economy and the internationalization of the market, people's requirements for clothing are gettin...
